Addition of an osmoticum (-12 bars) to the rooting medium of sunflowers (Helianthus annuus L.) caused an increase in the level of abscisic acid (ABA) present in xylem exudate subsequently collected from cut shoots.

We have studied two lines of sunflower (Helianthus annuus L.) selected in the field as drought-tolerant (RI genotype) or drought-sensitive (S 1 genotype). When subjected to drought conditions, the RI line was able to maintain high leaf water potential longer and wilted later than the S 1 line. There
